SAN FRANCISCO — Troy Tulowitzki believes he will soon return to form. Tonight, he returns to the cleanup spot after hitting fifth in Sunday’s loss to the Dodgers. The shortstop has admittedly been pressing, leading to anxiousness at the plate and a battery of flyball outs.

“I got here early today to work on my swing. I know I need to get better. It’s hard because we aren’t playing well as a team, and I know I need to do more,” said Tulowitzki, who has slumped in May along with the Rockies who enter tonight with 11 losses in their last 14 games.

The Rockies are 1-5 on this road trip and face San Francisco’s Ryan Vogelsong, whom they have never beaten. Todd Helton is starting at first base. He returned to Denver today to attend the funeral for former Rockies owner Jerry McMorris.

Tyler Colvin remains in center field, starting in front of Dexter Fowler. Fowler was hit in the face on a slide in Sunday’s loss, but is no longer bothered by blurred vision. Fowler has struggled offensively. And even while he’s not been as good as years past on defense, Carlos Gonzalez and Michael Cuddyer clearly are used to his range, which has created issues with Colvin in center.
